`4` claims. (ci. 259-7) j l l This invention relates to mixers of the class "especially adapted for mixingsolid materials of `different kinds and with a liquid binder, and has for the primary object the provision of a deviceof this. character wherein the materials will be caused to travel therethrough by gravitation, receiving a thorough `mixing during the travel thereof and which permits the device to operate by less power and with a less number of parts.

Another object of this invention is the provision of a device of this characterwhich willbe readily accessible for making repairs `and adjustments and whichmay be heated if desired. l

' l With these and other lobjects in View, the int nvention consists in certainnovel features of construction, combination and arrangement of parts to be hereinafter more fully described and" claimed. t

For a complete understanding of my invention, referenceyis to behad to the following description and accompanying drawings, in which Figure 1 isa vertical sectional view illustrating `a mixer `constructed in accordance with my invention.` t t Figure 2 is atop plan view illustrating the same.

Figure `3` is a fragmentary perspective `View showing one of the connections between a sweep or blade and a disc of the device.

Figure 4 is a fragmentary perspectiveview illustrating an adjustablehinged `type mounting usedin the mounting ofthe sweep or blade.

l Figure 5 is a detail sectional view `taken onxthe line 5 5 of Figure 1.

Referring in detail to the drawings, the numeral 5 indicates a vertically arranged cylindrical drum composed of companion sections equipped with barrels 6 through which extend removable tie rods 'I whereby the sections of the drum may be readily taken apart or detached for hinging movement relative to each other.

rI'he lower end of the drurnis equipped with `a "sectional discharge throat `8, the sections of which are secured on the sections ofthe drum. `'Ihe throat 8 supports centrally of the lower end `is `applied to theshaft `I3 in any well known manner.

, plates `or discs.

The ends of the spacer blocks have intertting connections with each other and clamp therebetween rotatable plates orfdiscs I5 adapted to l rotate with the shaft I3 and have their peripheries spacedifrom the walls of the drum. Each plate I5 is convex so that material falling thereon will slide in the direction of -the walls of the drum. t

Fixed plates or discs I6` are mounted on the walls of the drum and are arranged between the rotatable discs or plates andspaced an equaldistance therefrom and are provided with centrally arranged openings I1 through which the spacer blocks I4 pass freely and also provide passageways for the material of said plates or discs I 6 to gravitate therefrom centrally of the drum onto the plates or discs I5 thereunder. The plates or discs I6 are concaved so as to slope toward the `center of the drum `while the discs or plates I5 slope toward the walls of the drum. Therefore,

it will be seen that said plates I5 and I6 coact in bringing about an irregular passage of materials through the drum aided by gravitation. The

`plates or discs I6 are of sectional formation withV I6 with the separation of the sections of the drum.

Arranged within the drum are fixed and rotatablesweeps orblades I9 and 20 each being arcuately curved from end to end and provided with scraping edges for coaction with the plates or discs I5 and I6, it being understood that the `blades 'or sweeps have wiping contact with said plates or discs, the xed blades or sweeps coacting withthe rotatable discs or plates while the rotatable blades or sweeps coactwth the xed The xed blades or sweeps are hingedly connected to` mountings 2| adjustably secured on the walls of the drum 5` for vertical adjustment.

`The 4rotatable blades or sweeps are similarly mounted on the spacer blocks I4 for; rotation therewith. Adjustable tie means 22 are provided between `the fixed blades or sweeps and the fixed plates or discs thereover and similar adjustable tie means is provided between the rotatable sweeps and the "rotatable discs or blades. The adjustable tie means may be readily adjusted circumferentially of the discs or plates for the purpose of varying the radial pitch of the blades or sweeps and also permits the blades or sweeps to be adjusted toward and from the discs or plates for varying their wiping action thereon.

It is to be understood that the aggregate and liquid fluid is fed into the upper end of the drum onto the uppermost rotating disc or plateA and is contacted by the uppermost sweeps or blades which are non-rotatable causing said material to be swept from the uppermost disc or plate and toward the walls of the drum for depositing onto the xed plate or disc thereunder andis swept inwardly of the latter by the rotating sweeps or blades, consequently bringing about a Zig-zag passage of the material .through the drum under gravitation receiving a thorough mixing so that on reaching the discharge throat 8 the solid and liquid material will be efliciently combined with which also is of sectional formation, the purpose of `which is to permit heat to be injected therein for thev heating of the materials as they pass through the drum and during the time of receivingr the mixinfgzaction. i i

In use, rit is proposed that several units ofthe character described in connection with the showing made in Figure l may be so arranged that the materials discharged from one unit may be conveyed into the adjacent unit so that on the completion of travel of the materials through all of the units said materials then will be in a` Very highly mixed lstate ready for eiiicient use and further itis to be understood that the unit first receiving the materials maybe used as a hydrater by injecting heatinto the sockets there.- of and eliminating the injection of the liquid binder so that the solid material passing through the first unit willv be freed of any moisture con tents, it being understood that as the dried materials pass through the remaining units they' Awill be mixed lwith the liquid binder.k

-It is believed that the foregoing description when taken in connection `with the drawings will fully set forth the construction and advantages of vthis inventionto those skilled in the art to l which such'a device relates, so that further detailed description will not berequired.
